 Summary:
 Shrinkage is a time-dependent volume change of either fresh or hardened, unloaded concrete. One of the effective ways of crack-control in concrete is through the use of different types of fibers. Certain fibers significantly reduce plastic shrinkage in fresh concrete and are widely used in construction practice for this purpose, while other types of fiber reinforcement are used primarily for other reasons (eg, increasing the ductility of concrete). Both affect the drying shrinkage of concrete. This article presents the results of testing the drying shrinkage on fiber reinforced concretes. The experiments included the use of synthetic and steel fibers of different types, which are most commonly utilized as well as their combination. The drying shrinkage of concrete samples were measured for 120 days under controlled thermo-hygroscopic conditions.
